EMI/RFI-shielded Faraday tent

Cost-effective instant Faraday tent

The EMI/RFI-shielded Faraday tents are made of highly conductive, lightweight, and ultra-strong textile. By default the Faraday tents are delivered with multiple ropes so they can be easily attached to a ceiling, or they can come with a self-standing frame.

Typical applications are EMC experiments, RF measurements, mobile military or forensic activities, and personal protection in the field. Faraday tents offer a mobile solution for only a fraction of the cost compared to a conventional Faraday cage.

Applications

Computer and cell-phone forensics

Military field or embassy use

Secure or TEMPEST communication

Radar-jammer protection

Electromagnetic allergy / electrosmog

Pre-compliance testing

Temporary EMI shielding

Reverberation chamber (RVC)

Mode-stirred chamber (MSC)

Advantages

Easy to mount and move, mobile laboratory

Any size possible

Optionally supplied with a rigid reinforced floor

Single-layer Faraday tent: 40-60 dB up to 22.5 GHz

Double-layer Faraday tent: 70-90 dB up to 22.5 GHz

Additions (on request)

As illustrated in the technical drawing above, our Faraday tents can be supplied with the following options:

Rigid floor for heavy load (metal floor)

Solid floor for medium load (wood)

Shielded ventilation mesh / AC

Cable sleeve for entry of filtered cables, Ø80 mm

Shielded mesh window for visual contact

Standard closure with magnet strips

Power-line or signal-line filter according to your specifications

Led light inside (battery powered)

Led light inside (with power line filter on the net)

Data transmission filter (optical conversion, including wave guide)

Packing/transport bag

Many other options on request

Please note: when you want to enter the tent with heavy equipment like vehicles, planes, tanks you need a rigid floor and a tent with magnetic strips to the bottom so that the entrance to the tent can be fully opened.

Mounting options

Our Faraday tents can optionally be supplied with a mounting frame so they can easily be set up as a stand-alone structure almost anywhere, but they are usually supplied with mounting ropes to attach to a ceiling. Mounting ropes are generally used when the Faraday tent is installed inside a building in a permanent location.

Standard sizes / shapes

We have a number of Faraday tents in standard sizes and shapes in stock. In addition, almost any size and shape can be made on request. Feel free to send us a technical drawing of the desired Faraday tent. Sample drawings can be found under Technical drawings on this page.

Please note : All measurements given in the tables below are outer dimensions. In a dual-layer tent, approximately 10 cm is lost on the inside of the tent. So when you order for example a 2 meters wide double layer shielded tent, the inside wide will be 1.90 meters.

How to set up the Faraday tent

Setting up the Faraday tent takes little time and is quite easy.

The standard Faraday tent is supplied with ropes, so that the tent can be suspended from the ceiling. Optionally the Faraday tent can be delivered with a convenient mounting frame and/or plastic locks as shown in the picture below. With the plastic locks on a double-layer Faraday tent it is easy to connect the inner Faraday tent to the outer one.

Faraday tent aka EMI shielded tent with a rigid floor for heavy load

Our Faraday tents can optionally be supplied with a very strong Mu-ferro floor. This floor is much sturdier than the original tent floor. With this floor, it is possible to drive, for example a car in the tent

Shielded ventilation mesh

Shielded ventilation mesh

Our Faraday tents can optionally be supplied with a shielded ventilation mesh. A double layer of fine conductive wire mesh can be installed allowing you to have fresh air or air conditioning inside the tent

Cable sleeve for entry of filtered cables Ø80 mm

Cable shielding sleeve

The cable entry sleeve can be used for entering shielded cables or already filtered cables. if you do not use filtered cables or shielded cables they will work as an antenna, and they bring in unwanted frequencies inside the shielded tent .

Visual contact (Mesh window)

Maintain visual contact with your experiment

A double layer of fine conductive wire mesh can be installed allowing you to maintain visual contact between the inside or outside of the tent

How to access the Faraday tent

Faraday-tent access with magnetic strips

Typically the access point is provided with magnetic strips covered with electrically conductive layers of textile. The magnetic closure ensures superb electrical contact when the tent is closed. On request, the entrance can also be equipped with conductive Velcro strips.
